Specication of certain improvements in Cork-Screws, invented by WILLIAM H.' VAN GIESON, of Passaic, in the county of Passaic, and State of New Jersey.` p

The object of my inventioii is to produce fa cork-screw which shall be rapid and simple in its operation, as well as strong and durable, and not too bulky to be convenient in handling.

To accomplish this object, I attach to the middle'of the handle a metallic tube, in the position usually occupied by thc shank of the instrument, and extend the shank of the screw or spiral to about double its usual length,

making the upper part in the form of a regularly twisted square,\or other prism-shaped rod, having about one twist to the inch, and turned in the opposite direction from that of the screw or spiraly itself, and make this twisted square portion to run up into the said tube through a plate at its lower extremity. This plate has a hole throughit, of the exact form of the twisted rod, acting on the rod in the manner of a screw-nut, so that as the rod passes up into the tube, it is caused to revolve on its axis,pthus driving the screw o'r spiral 'into the cork against which it is pressed. When 'the twisted square rod is thus driven up into the'tube, and the screw or spiral into the cork, a spring-catch, which is fastened to the lower end of the tube, -catches under a shoulder at the lower end of the square rod, where it joins thc shank of the spiral, and holds it securely while the cork is being withdrawn. The cork can `be remoxed. in the usual, way, or` the spring-catch may be disengaged, and the twisted part drawn out, ready -for'use again. In the last case the cork would be run ofi' from the spiral at the same time. In the accompanying drawings-- I i Figure 1 is a side elevation of my improved corkscrew, with the twisted part within the tube;V

Figure 2 is aside elevation of the same, with the stem drawn out.

Figure 3 is a cross-section, through z pz, tig. 1, showing the spring-catch thrown out.

Figure 4 is a similar section, with the'spring-catch'locked under the shoulder on the shank or stem.

Figure 5 is a cross-section, through the line x :13, iig. 1.

Figure 6 is a cross-section, through the line y y, fig. 2. v

The shank or stem of the cork-screw consists of two parts, the spiral or screw part, A, which cuers the cork for the purpose of pulling it, and which is or may be constructed in the'usual manner, and the twisted por` tion B, which is simply a square or other prism-shaped rod, twisted in the direction the reverse of that of the spiral or screw A. At the junction of these two parts there is a shoulder, C. At the upper end of the part B there is a head or button, D, (shown in dotted lines,) which preventsnthe said part B from coming entirely out of the tube. E is the tube and F the handle. The tube E is secured in the handle F by the rivet or pin'G.' At,`

the lower extremity of the tube E, thc twisted rod B passes through an opening in the plate H,gs. 5 and 6, which is securely fastened to thetube E, thc said opening being of the form of a section ofthe said twisted rod, so that when the rod is forced through the said opening, either into or out of the tube, it is caused to revolve, thus operating the spiral or screw A. The pitch'rof the twist of thc part Bis very steep', sothat it may be forced through the opening in the plate H with comparative ease, that exhibited in the drawings being intended to represent about one full turn to the inch. I is aspring-catch, which is hel'd up against the stemby the circular spring J, and which is set into a slot 4inthe end of the tube, so as to give it great strength to resist the eiieets of Vthe force applied tothe cork-screw in using it. It is pivoted on a pin, a, in tlfe end of the tube E, and has an additional pin, b, insertedA in it, which prevents the spring-catch from being thrown out too Afar by striking against the-end of the slot c.

In using my cork-screw, the stem is rst thrown out, which can'easily be done by pressing back the springcatch I, and the point of the spiral or screw A being placed against the centre of the cork, the handle is forced down, thereby turning the twisted part'B and spiral A, and forcing the said spiral into vthe cork. So soon as the shoulder C passes above the spring-catch I, the said springcatch hooks under the said shoulder, and'gives a bearing againstwhich the stem is supported while the cork is being pulled. The" cork may be easily drawn i from the cork-screw by throwing the spring-catch I out and pulling it oii', the ste'm meanwhile running out.

With th'is instrument it takes but an instant to draw a cork, while the cork-screw itself is simple, durable, and easily manipulated. i

Having thus fully described my invention, I claim- 1. Constructing the upper part B of the stem in the form of a twist, spiral, or screw, turned in a direction the reverse of that of the lower part A, substantially as and forthe'purpose set forth.

2. The combination with the stem A B, constructed substantially as described, of the tubeE., plate H,'or its equivalent, spring-catch I, and handle F, the whole working-together in the manncr'and to accomplish the vresult set forth.
